Kernel / Systems Programmer

Impact: Infrastructure / Platform Impact

Develops and maintains operating system kernels, device drivers, hypervisors, and low-level system software, working at the intersection of hardware and software.

From people doing the work

Working as a Kernel/Systems Programmer is a constant intellectual challenge. You spend your days deep in code, debugging intricate issues that can bring down an entire system. It requires patience, a careful eye for detail, and a passion for understanding how computers work at their most fundamental level. The satisfaction comes from optimizing performance, fixing critical bugs, and contributing to the core of widely used systems.
